Hi, I'm J2M from France. I have anything for putting the firmware back to my R36, but I'm not a specialist and I can't understand the procedure.Is there someone to help me, for settings and process? It will ber great. Thanks a lot. (If you speak french it's more better!!!)

Yes, i am having some issues.. im not getting any output in hyperterm when i plug in the r36. im using windows 7 with a usb to serial device connected to a rs232 to TTL converter. Hyperterm is configured to the specs in the video, wondering if i have the pin out correctly on the R36.
